LOOK FOR IGNITION AND LIGHTING SWITCHES.

Application filed ma 24, 1920. Serial No. 383,667.

My invention relates to electrical switches lighting switches such asare used for controlling the. lighting and ignition circuits of anautomobile or the like. An object of my in- .ventlon is to provide adevice of the above character which contains novel features ot'construction and con'ibination of parts, all of which produce a simpleefficient and economical switch structure. v l

A feature of my invention isthe provision of a lock of the pin tumblertype, which is used for locking the lighting and ignition units of theswitch against actuation, that is,

when the locking unit is in one position, the switch units are free tobe actuated, but when the locking element is in itsalternate positionthe switch units are locked against actuation. The pin tumbler cylinderlock of my invention is of novel. construction, comprising a tumblerextension provided with two sets of pintumblers in association with oneset of pin tumblers in the key barrel. This method of constructionpermitsthe key to beoperated through only a small degree of rotation toeither lock or unlock the locking element of the switch, and the key mayalso be withdrawn without the necessity of making a complete rotation ofthe key barrel, as is the case with the present types of pin tumblercylinder locks in use.

Another feature of my invention is a novel spring arrangementinassociation with a rotatable cam button for controllingthe actuation ofthe said springs. The said springs control the cowl light circuit of theswitch of my invention, but it is to be understood that it may be usedfor other purposes without departing from the scope of my invention.

The above features, as well as others, consist in the novel details ofconstruction and combination of parts hereinafter more parlingmechanism, the cap of the switch being removed v Fig. 5 is a left sideviewof Fig. 4.-

Referring now in general: to my invention as illustrated, it comprises alighting switch unit L and an-ignition switch unit M. The

lighting switch unit L has a normal or otf position A and threeoperative positions B, C and I). In position B the side lights of theautomobile lighting system are connected in circuit, in position C theauxiliary lights are connected in circuit, and in position D the headlights are connected in circuit but I do notwish be limited to thisparticular arrangement, as different combinations can be used withoutdeparting from the invention.

pin-tumbler, cylinder typelock T, which con *trols a sliding lockingplate LP, whichis adapted to lock the lighting and ignition switchunitsL and M'againstactuation.' The locking mechanism is so arrangedthat it operates only when the ignition switch uiiitM is in its normalor off position E, but Will -operate to lock the lighting switch unit Lin its positions A, B and C; but when in position D the lock cannot beoperated. WVhenthe ignition switch unit M is in its position F, the lockT can only be turned part way by the key. Now, if the operator attemptsto operate the lock T, he is at once aware that the ignition switehunitM is in its operative or or? posi tionF or the lighting switch unit L isin its D position; I i r The cowl light control button'CL and itsassociated springs are provided for controlling the circuit of the cowllight, as will be moreparticularly pointed out in the followingspecification.

Re e'rring now' more in detail to my-invention as illustrated, itcomprises, preferably, a mounting plate 2 made of anysuitable'insulating material such as bakelite, and having studs 3 and 4fastened to it ili any-suitable manner, as by means of the nuts 5, whichnuts 5 have screwthreaded engagement with the threaded portions of thestuds 3 and 4, which extend beyond the rear face of the plate 2.

The plate 2 is provided with a peripheral ridge 2 extending upwardlyfrom the plate proper. The plate is also provided wlth a flange uponwhich the cover cap of the device rests. The stud 3 is provided for theignition switch unit M and the stud 4 is provided for the lightingswitch unit L. Springs 6, 7 and 8 are associatedwith the ignition switchunit M, and springs 9, 1.0, 11, 12 and 13 are associated with .thelighting switch unit L. Springs 6, 7, 8, 9,,ete., are similarlyeonstrueted so that, by describing one of them, the construction of theothers is readily apparent. r y i tongue or terminal blade 14 ofsuitable conducting material is provided with an intermediate reducedportion 15 and a further reduced end portion 16,,which reduced portions15 and 16 form shoulders 17 and 18 upon the blade 14. The blade 14 isforced into a suitable opening 19 in the, plate 2, which opening isslightly smaller than the interim diate reduced portion 15, so as toprovide a force-fit. The blade 14 when in place has its.

shoulder 17 engagingthe face of the ridge. 2 of the plate 2, andtheshoulder 18 formed by the end reduced portion 16 protrudes slightlybeyond the bottom face of the plate 2,7and this protruding shoulder 18is upset to hold the blades14 against lateral movement in the opening 19of the plate 2. The spring 8 is formed out of spring metal and is prothe said spring 8 to the blade 14.

The free end of the spring 8 is provided with a rounded or curved endportion which fornisacontactingend which engages its associated switch.unit. The portion .16 of-the blade 14 which extends beyond the bottomsurface ofthe plate 2forms a connecting terminal for the spring 8 and isprovided witha saddle or clampingmember22,which provides means forsecuringan electrical conductorto the terminals formed by the portion16.v Screws 23 areiprovided with washers 24, which screws 23havescrew-threaded engagement with the clamping members 22 vfor securelyholding theelectrical conductor between the portion 16fof the blade 14of its associated spring 6 and the saidclamping member 22. y a 7Associated with the combination ignition switch. as illustrated, I showan overload relay OR, which isused for purposes well understood. Therelay OR is secured to the supporting plate 30 in any suitable manner,and its supporting plate 30 is in turn secured tothe studs and 4'bymeans of the nuts 31, whichnuts 31: have screw-threaded engagesmentwiththe threaded portions of the studs 3 and 4.

The lighting switch unit L and the ignition switch unit M are eachprovided with a rotor element, and as both are similar in construction,a 'description ofone ofthem will suffice; The rotorelementassociatedwiththe lighting switch unit L comprises a supporting stud 32, aholding'disc .33 for holding the lighting switch unit L in its difierent'posi--tions, washers 34 and 35,a sleeve 36 of suitable insulating material,cams 37 and 38 of suitable insulationmaterial, a cam 39 of suit ableconducting materialand a washer 40, which members are all supported uponthe stud 32. The disc 33 is provided with anorifice of a size to permitits being slipped over the bodyportion 41 of the stud 32, and when thesaid member 33 is in place, it rests against theshoulder portion 42 ofthe stud 32. The

insulation sleeve 36 is provided with an orifice of a 'size toperm-itits being slipped over the body portion 41 of thestud 32, the'said sleeve 36, when inplace, resting, against the member33. Washers 34 and35 are provided with orifices of a size topermit their being slippedover the insulation sleeve 36, andJthe cams 37'and 38, which are ofsuitableinsulation material, are also provided with orifices 1 41 of thestud 32 protrudes slightly beyond washer 40, and this portion is upsetor spun over, securing the said members upon stud 32 againstdisplacement. Y v

To prevent the membersj33, 34, 35, 37, 38, 39 and 40 from rotating aboutthe stud 32, I provide a pin 43, which is secured to the member 33, thesaid pin 43 extending through shoulder portion '42 and the stud 32.

the members 37, 38and 39, but insulatedfrom the said members 39 by meansof a sleeve of insulation 44 through which the'said pin 43 extends. Themember 33 is also secured to the stud. 32 by means of a pin 45, the saidpin 45 passing through the member 33 and lt he 1e stud 32is alsoprovided with a central opening 46 of a size to receive the supportingstud 40f the lighting switch unit L, to permit the rotation of saidlightingswitch unit rotor. The insulation cams 37 and 38 are pro- Ivided with wing portions 47 and 48, and the metallic member 39 isprovided with wing portionsi49' and 50', which wings cooperate with thefree ends of the springs 9, 10, 11,- 1 2 and 13, when the lightingswitch-unlt L is moved to its several positions, as is readilyunderstood.

The cowl light controlunit CL comprises a leaf spring secured to aterminal blade 14 by means of screws 21, as already described,

and I illustratethecowl unit CL in Fig. 4

in its normal or inoperative position. A shaft 61 rotatably supported bythe mounting plate 2 in a suitable bearing 62 has secured thereto arectangular shaped cam member 63, which cam member 63 is held in placethereon by means of a pin 64. The cam member 63 is provided with areduced cylindrical portion 65, which forms a shoulder 65", whichrestsagainst the face of the mounting plate 2. To hold the cam member 63in either its normal or operative positions against rotation, I providea leaf spring 66 secured to the terminal blade 14 by means of the screws21. When the cam'member 63 is in its normal or inoperative position, the

free end 67 of the spring 66 engages a wide I face 68 or 690i the cam,63, depending in which direction itwas rotated when placing the said cam63 in its normal position, and

' this holds the said cam .63 in its normal posi- 'tion, The cam 63 maybe rotated either to respectivelyyin any of their difierent the right orleft to movethe cowl light spring 1 60 to itsoperative position. .Uponrotation of the shaft 61, a camapex 70 of the cam 63 engages the leafspring66and in-turnforces the'free'end '71 of the spring 60 intoengagement with the terminal'blade 14 of the spring .13. -Whenthe apex70 passes beyond its highest pointin its rotation, the tension of thefreeend 67lof theispring 66 force's t-he further rotation of. the .cam63, producing a 1" snap action. The cam 63 when in operative positionhas its peripheral face 72 or: 73 engaging spring66 to hold the treeend'7;1= of springg60 in engagement. with the terminal" blade 14 of.spring. 13, as :illustratedin Fig. 10. Now,;to restore thecam 63 toitsin'operatiw e position, it-may be rotated to the right orleftycausingaflcam apex 70 to again engage thefree end 67 of thespring'66, and

when the apex passes beyond itsv highestpoint in itsrotation,.thetension ofjthe free end 67 of spring 66is. such as toforcexfurther rotation, which produces a snap action,

again placing thefree end 67 ofthe spring 66 in engagement with a face68 or 69,depending in which'direction the. cam was rotated to restore itto its normal position: .VVhen the cam is in the position so that theend. 67 of spring 66 again engages a face 68 Jor,69 of the .camc63, thefree end 71 of the spring 60 disengages the blade 14 ofspring 13,againopening the cowl light circuits The holding member 33isin-the iiormof a notchortoothedxdisc, an'd to cooperate with the discs 33 and 33.to'yieldinglyhold the lighting and ignition switch units Land M,

ositions, I provideaa holding device H w 'ich comprisesa centrallypivoted member, 51, a which carries rotatable rollers 52 and 53 in itsbifurcated ends,asaid rolle'rs52 and 53 operating in connection. withthe discs 33 1 and 33 of the ignition switch unit,M and the light-ingswitch unit L. 1 The member-51 is pivot-ally supported at'its center bya stud 54,

which is suitably fastened to the mounting plate, 2 by means of a nut55, which nut55 has screw threaded engagement with-the threaded portionof the stud 54.v A spring 56 for yiel'dingly holding memberH against thediscs 33 and 33 of the switch unitsL and M is provided. ';.The free endof, the

spring -56-rests against the bridge: of the member the other end'o'f thespring 56 being fastened to the mounting-plate 2 by means of a. screw 57and nut 58. Whenone of the switchmembers is operated, the teeth of itsdisc are' rotated against its associated roller, dueto the action of thespring 56, and as the disc.33 advances the roller acts upon the nexttooth notch so as to give a snap action to the switch member and at thesame time hold the actuating members of the switch in place. A lockingarrangement s provided whereeachother, the two sets of tumb1ers 83 and 81 beingplaced at-aforty five degree angle from' "each other. sox'thatthe key 85 is rotated through onlyvforty-five degrees of movement by thelightingand ignition switch units L and M maybe locked injtheirdifferent positions. I, therefore, provide. a pin tumbler cylinder lockT which cooperates with: a sliding locking plate LP. The cylinder lock Tcomprises a lock case 80; Whichlockcase 80 1S provided with a tumblerextension 81, and

rotatably mounted in the lockcaseg8O isthe key barrel or cylinder 82.}The pin tumbler lookT-coniprises-two sets of in tumblers'83 and 84.;angularl-y displaced in relation with V g to place the lock infa lookingor unlocking position. "The two sets of pin tumblers 83 and 84 rest insuitable orifice's'86 in'the tumbler extension 81 and arespring-pressedtoward the cylinder 82-by means of thecoil spring 187. Thepin "tumblersets 83 and 84 are in duplicate for purposes as will presently bedescribed.

The key barrel 82 extends rearwardly from the casing 80, andthisrea'rwa-rdly extending "portion 93 rest-s in a pocket ordepression9-1 in the mounting plate 2. The tumbler-extension is provided with apin 95 suitably secured to it. and this pin'95 rests in a suit- "ableorifice 96 of a size to receive the said pin The lock barrel 82 restingin the pocket 1 i tion of the samein thesaid pocket/94,- when r thesaidkey 85 ofthelock is turned. The

sliding locking plate LP, which is provided for-locking'the switchingunitsLL and M so To permit movement of the that theycannot be operated,-consists of a plate97 providedwith elongated slots 98 and i 99, throughwhich thestuds-Ziand 4 extend.

The plate 97 is also provided with a U-shaped notch 1000f a size topermit it to span the 'lock barrel 82 whichrestsin the pocket 94 in themounting plate'2, and isialso provided with a smallerU-shapedLnotch[101of a size to permit it to span the pin95; The slots 98and 99a11dthe U-shaped notches 100 and 101, in association with thestuds '3 and 4 and i the key barrel 82 and pin 95 iform guiding meansfot'the-plate 97; whenthe said plate is moved to lock or unlock theswitch unitsL and M, asthe case may be. 1 i plate 97 when the key 85 isrotated to lock orunlockthe switch units L and M,I provide a pairpf pinsand 106 which'are securedtothe rearwardly extending portion oi" the key'barrel82, the said pins 105 and lOficooperating with a pin 107' whichissecured to the sliding locking plate 97 in any suitable-man-.ncr',-the said pin'107 resting between the pins 105 and 106 ofthe'barrel 82.

'ing. the mechanism at normal. To look the switch units L and M, thekeyot the lock T is inserted and turned to the right causingthe pin 106in the key barrel 82 to engage-the pin 107 in the plate 97. Continuedrotation of the key in the lock T moves the plate 97 in an upwarddirection into the position shown in Fig. 9. The extensions 108 and 109enter the slots 33 and 83 of the switching units M and L, respectively,preventing the movement of said units, To unlock the switch units L andM, the key is turned to the left, causing the pin 105 to engage pin 107to move the plate 97 iii a downward direction, and this downwardmovement'ol the;

sliding locking plate 97 withdraws the exten sions 108 and 109 from theslots 33 and 33".

To yieldingly hold the plate 97 iii itslocked or unlocked positions,-Iprovide a flat'spring 115 secured between the member and the plate 2bymeans of the stud 54,'which holds the plate 97 in its differentpositions, the free end of the spring 115 engaging the slid ing plate97; the spring115 alsoserves to maintain the key barrel 82 in itsadjusted,

positions by preventing movement of the plate 97 which is provided witha pin 107 which engages the pins 105 and 106011 the" key barrel 82 toholdit against rotation. cover or casing 116 ispi'ovided for enclosingthe mechanism, and a top plate 117 isalso provided, as is also a'nameplate 118, the said cover 116, plate 117 and name plate 118 being heldtogether in any suitable manner and i being provided with suitableopeningsto permit the passage of the studs3 and 4 and shaft 61 of thecowl controlunit CL. Handles 11.9 and 120 are secured to thestuds 3 and4 in a bearing for the head 82' of the key barrel 82 when it isrotatedby the key.

From the above description, itwill seen that with the cylinder lockmounted'with the,

rearwai'dly extending portion 93 of the barrel 82 resting in the; pocket94 and the pin:

resting in the-orifice'96 and the. barrel head 82? projectingthroughtheopening 122 in the I casing 116, the lockwill'be'rigidly secured inplace between the casing 116 and the mounting plate 2. The openingthrough which the head 82' of. the key barrel 82 projects and therear-portion 93 of the barrel 82 whichrests in thepocket-t94 in themounting plate 2 both serve as bearings for the barrel- 82 when it isrotated by the key, the said pocket 94 also seating tlie'lock inposition. The shoulder 123 formedby the barrel casing 80' abuts againstthe inner surface of the cas-, ing 116, preventing displacement ofthelock in the pocket 94, and thepin 95 resting in the orifice 96 preventsthe lock from rotating-as 'a whole when the key is turned. i

From the construction herein described,

it will be apparent that it is unnecessaryto rigidly secure the'lock toany memberof the switch or casing, because when thecas ing is secured to'the plate 2 by means of nutsnot shown on the 'di'awing, the lock willbe clamped between tl1e-casing 116 and mounting plate The switch rotorsare also held in pos tion by the cover casing.

Referring now-to Figs. 15 and 16, 1 illustrate another method ofcontrolling theslid-' ing locking plate'97 as to its movement to alocking andanunlocki'ngposition. In the above figures I-onlyillust-rateafragmentary portion of the switch structure which is thesame asdescribed in connection with Figs.

1 to 14, inclusive; The lock T as shown is ofa; construction similar tothat shown and described in connection with Figs. 1 and 14, inclusive.In the instancef'of Figs. 15 and 16, I'show the barrel extension 93provided with a pin 130 suitably securedthereto and operativelyassociated with ap'air ofpins 131 and 132 suitably secured to'thesliding locking plate 97, the said pin 130 of'tghe barrel extension 93res'ts between these pins 131 and 132 of, the plate 97 Now, when thekey'is inserted into the key slot 91 of the barrel' 82,and rotated, the saidbarrel82 is rotated therewith and the pin 130 in-the barrel 82 engagesthe pin' 131 secured to the plate 97 and moves'the said 1)] ate 97upward,andtl'ie extensions 108 and 109 of the plate enter the slots 33and '33 of the switching units M and L, respectively, preventingmovement of the said units; To unlock theunits'M and L, the keykl5isrotated to the 'lett and the 7 barrel 82 rotates therewith, causingpin-130 secured to the said barrel 82 to engagejthe pin 132 secured totlie plate' 97 and move it in a downward direction, and this down: wardmovement of the sliding locking plate 97 withdrawsthe extensions 108and'109 of the'plate 97 from the slots 33 and 33 The spring serves tomaintain the locking" plate 97in its adjusted positions and through theagencyflof the plate 97 and pins 1'31 and 132 secured thereto and pin ontheakey barrel- 82 thekey barrel 82 prevented fromunauthorized oraccidentalrotation when the V lock is in either a lockingor an unlockingPosition.

'Referr ngnow to Figsl17and is, I nitstrate anothermeansfor-Controllingthe cowl 6 light circuit, In' the abovefigures'I-only il-- lustrate a fragmentary portionof the switch:

structure which is the same as described in connection with Figs. 1 to14, inclusive. a The cam member 63 and itsparts as shown are of aconstructionsimilar to that shown a and described in connectionwithFigs. 1 to 14;,

inclusive.

To hold the cam its, operative or inoperative positions aga nstrotation,I provide a contact, spring 135 se-' cured-to the mounting plate 2 inany suitable manner, and itsfree end 136, when thecmn;

Inember63is in its normal position, engagesa Wide face 68 or 690i? thecam 63, depending upon which direction it was rotated when placingthecam 63 in its normal position, as

' illustrated in Figi17i The spring 13 of the light switch unit Lis'provided with an ex:- tension13 which is bent back so that itsextended :portion 13 is parallel with the body portion of thespringllf-i'; The spring 135 and the extension 13 forn'rt-he circuit;clos;

ingyrme'a ns for the cowl light circuit. The cam 63; may be rotated ineither direction forces the further rotation of the cam 63, producing asnap action. The cam 63'When in itsoperative position, in which positionit holdsnthe spring 135 and extension113 in closed relation, isillustrated in F ig.;18, and When in this positionthe free end 136 ofthe spring 135 engages either peripheral face my invention; it isyto beunderstood-that changes and modifications Willreadily sugge'stFthemselves tothose, skilled in the art,

72 or 73 of the cam63 tohold the cam 63 in its 1 operative position. Toopen the covvl circuit, the cam63 is again rotatedin either direction,causing {LyCELIIl apex to again engage the freeend 136 of spring135, and

when the apex passesbeyond'its highest point t ,in its rotation, thetension of the spring- V causesa snap action and the end 136 of spring135 again engages a face 68 or'69 of the cam63. i

From the foregoing it isat once apparent thataI-have so arrangedthe,lock mechanism that it is never necessary to rotatethe lock f barrelOneCOlIlPlQtGl'QVOhItlOIl; With lock mechanism of the prior art type, agreat deal of trouble and inconvenience s encountered in rotatingthelock mechanism a complete revolution, and especially so if thelockkey is attached toaring ofkeys.
